Twelfth Night, or What You Will is a comedy by William Shakespeare. The play is named after the Twelfth Night holiday. It was written to be performed as part of Twelfth Night celebrations and first performed at Candlemas, February 2, which was then the culmination of the long winter feast, at Middle Temple Hall, London by Shakespeare's company, the Lord Chamberlain's Men. The presumed time of the play's composition is between 1599 and late 1601.
